Posing tips please

As I have noticed with alot of the movie line like say Sideways, They are very top heavy with small feet. So here is my problem, I have quite a few transformers like this, when I get home, I have 2 100 pound dogs that go nuts and start running laps around my living room. This will shake the curio cabinet that some of these are in and cause some of them to fall over,, sometimes with a domino effect.

Are there any tips out there for posing these figures to make them a little more stable?

Small wads of blue-tack (or yellow) on the feet to give it a little extra stick to the surface. Doesn't harm the surface or the figure. I got a pack with 5 sticks of yellow-tack for $2 (enough to stand 100 figures or more) - it's awesome for so many hobby related things and you can find it in almost any hardware store.

I often take my most unstable figures and place them in the back of the shelf resting up against the wall
(and in some cases use the stable ones as a sort of "kickstand") to make sure nothing moves around to much.

The blue tack and bent knees does work well but when I tried the blue tack it left a residue (on the wood of the cabinet)
and collected quite a bit of dust by comparison at the feet.

If all else fails don't forget that the alternate mode (jet, car, or whathaveyou) is often more shelf stable than any bipedal robot.

Pose Sideways in a barrel roll sort of like the roll he did in the Shangai chase through the house with the Arcees following him.

I know for a few weeks there I had Sideways in car mode with Sideswipe above him slicing through him. You can squeeze Sideswipes sword in between the gaps in Sideways bonnet and have him slicing through Sideways. Can't take pictures at the moment as my figures are in storage but will as soon as they come out.
